The first phase of Hefei Changxin 12-inch memory wafer manufacturing base covers an area of 566,000 square meters and a construction area of about 490,000 square meters. As a major "mysterious team" among China's three major memory forces, Hefei Changxin plays an important role in domestic DRAM.
Chip safety production faces challenges
If there is a temporary voltage pause or power failure in the power supply of Hefei Changxin 12-inch memory wafer manufacturing base, it may lead to the production suspension of chip factories, equipment damage and even chip scrapping, which will bring huge economic losses to enterprises. This puts forward extremely high requirements for the quality of power supply and distribution, and also brings arduous challenges to the quality of power supply and distribution services of manufacturers.
Due to the huge production scale and diverse functions by region, in order to ensure normal power supply, the power supply and distribution system of Hefei Changxin Phase I project adopts two 20kV dedicated lines for city power supply and direct conversion to 0.4kV for factory use, and the low-voltage system has 12 25,000kW generator sets as emergency power supply, and the front end of important loads is equipped with UPS uninterruptible power supply. Professional power distribution system design avoids unnecessary losses caused by power supply interruptions.
The security cornerstone of domestic storage mysterious forces
With deep technical research and development accumulation and rich experience in smart factory projects, combined with the actual application needs of customers, TYT has designed a set of stable and reliable and technologically advanced intelligent power distribution solutions for Hefei Changxin, including TYT TBBQ6 series dual-power automatic transfer switches, which help this top domestic storage manufacturing base achieve safer and more efficient operations.
TBBQ6 series dual-power automatic transfer switch adopts a dedicated PC-level integrated design, and the performance is more reliable than the derivative products. The use category is up to AC-33A, and there is no fear of the impact caused by the electric motor or high-sensitivity load switching, which can ensure the stable power supply of large water pumps in the factory area. The excitation drive ensures that the conversion time is < 100ms, and the power supply continuity is high, which meets the power supply of important load equipment such as production equipment and DAU data acquisition and transmission instruments in the factory area.
At the front end of key equipment with extremely high power supply continuity requirements, it is also equipped with a dynamic UPS with excellent power quality, high efficiency and strong load capacity. Because TBBQ6 series products have the function of neutral line overlap conversion, it effectively avoids the problem of neutral potential drift caused by neutral wire potential drift caused by neutral wire disconnection during the conversion process.
TYT dual-power ATSE can integrate intelligent power distribution management, and can be connected to the TYT FUTURE intelligent cloud distribution management system through Ethernet, 4G wireless communication and other communication methods. The system integrates TYT intelligent power distribution equipment, edge communication and conversion technology to build a leading intelligent power distribution system. Based on the Internet of Things and cloud data storage analysis, multi-platform mobile management is realized.
